• Reject ask user question tool in Execute and Custom (#9560)

  ## Summary
  - Keep `request_user_input` in the tool list but reject it at runtime in
  Execute/Custom modes with a clear model-facing error.
  - Add a session accessor for current collaboration mode and enforce the
  gate in the request_user_input handler.
  - Update core/app-server tests to use Plan mode for success and add
  Execute/Custom rejection coverage.

• Prompt Expansion: Preserve Text Elements (#9518)

  Summary
  - Preserve `text_elements` through custom prompt argument parsing and
  expansion (named and numeric placeholders).
  - Translate text element ranges through Shlex parsing using sentinel
  substitution, and rehydrate text + element ranges per arg.
  - Drop image attachments when their placeholder does not survive prompt
  expansion, keeping attachments consistent with rendered elements.
  - Mirror changes in TUI2 and expand tests for prompt parsing/expansion
  edge cases.
  
  Tests
  - placeholders with spaces as single tokens (positional + key=value,
  quoted + unquoted),
    - prompt expansion with image placeholders,
    - large paste + image arg combinations,
    - unused image arg dropped after expansion.

• fix(core): require approval for force delete on Windows (#8590)

  ### What
  Implemented detection for dangerous "force delete" commands on Windows
  to trigger the user approval prompt when `--ask-for-approval on-request`
  is set. This aligns Windows behavior with the existing safety checks for
  `rm -rf` on Linux.
  
  ### Why
  Fixes #8567 - a critical safety gap where destructive Windows commands
  could bypass the approval prompt. This prevents accidental data loss by
  ensuring the user explicitly confirms operations that would otherwise
  suppress the OS's native confirmation prompts.
  
  ### How
  Updated the Windows command safety module to identify and flag the
  following patterns as dangerous:
  *   **PowerShell**:
  * Detects `Remove-Item` (and aliases `rm`, `ri`, `del`, `erase`, `rd`,
  `rmdir`) when used with the `-Force` flag.
  * Uses token-based analysis to robustly detect these patterns even
  inside script blocks (`{...}`), sub-expression `(...)`, or
  semicolon-chained sequences.
  *   **CMD**:
      *   Detects `del /f` (force delete files).
      *   Detects `rd /s /q` (recursive delete quiet).
  * **Command Chaining**: Added support for analyzing chained commands
  (using `&`, `&&`, `|`, `||`) to separate and check individual commands
  (e.g., catching `del /f` hidden in `echo log & del /f data`).
  
  ### Testing
  Added comprehensive unit tests covering:
  * **PowerShell**: `Remove-Item -Path 'test' -Recurse -Force` (Exact
  reproduction case).
  * **Complex Syntax**: Verified detection inside blocks (e.g., `if
  ($true) { rm -Force }`) and with trailing punctuation.
  *   **CMD**:
      *   `del /f` (Flagged).
      *   `rd /s /q` (Flagged).
      *   Chained commands: `echo hi & del /f file` (Flagged).
  *   **False Positives**:
      *   `rd /s` (Not flagged - relies on native prompt).
      *   Standard deletions without force flags.
  
  Verified with `cargo test` and `cargo clippy`.

• Improve UI spacing for queued messages (#9162)

  Despite good spacing between queued messages and assistant message text:
  <img width="462" height="322" alt="Screenshot 2026-01-12 at 4 54 50 PM"
  src="https://github.com/user-attachments/assets/e8b46252-0b33-40d2-b431-cb73b9a3bd2e"
  />
  
  Codex has confusing spacing between queued messages and shimmering
  status text (making the queued message seem like a sub-item of the
  shimmering status text)
  <img width="615" height="217" alt="Screenshot 2026-01-12 at 4 54 18 PM"
  src="https://github.com/user-attachments/assets/ee5e6095-8fe9-4863-88d2-10472cab8bd6"
  />
  
  This PR changes the spacing between the queued message(s) and shimmering
  status text to make it less confusing:
  <img width="440" height="240" alt="Screenshot 2026-01-13 at 11 20 36 AM"
  src="https://github.com/user-attachments/assets/02dcc690-cbe9-4943-87de-c7300ef51120"
  />
  
  While working on the status/queued spacing change, we noticed two
  paste‑burst tests were timing‑sensitive and could fail
  on slower CI. We added a small test‑only helper to keep the paste‑burst
  state active and refreshed during these tests. This
  removes dependence on tight timing and makes the tests deterministic
  without affecting runtime behavior.

• fix(cli): add execute permission to bin/codex.js (#9532)

  ## Summary
  Fixes #9520
  
  The `bin/codex.js` file was missing execute permissions (`644` instead
  of `755`), causing the `codex` command to fail after npm global
  installation.
  
  ## Changes
  - Added execute permission (`+x`) to `codex-cli/bin/codex.js`
  
  ## Verification
  After this fix, npm tarballs will include the correct file permissions:
  ```bash
  # Before: -rw-r--r-- (644)
  # After:  -rwxr-xr-x (755)
  ```

• Add total (non-partial) TextElement placeholder accessors (#9545)

  ## Summary
  - Make `TextElement` placeholders private and add a text-backed accessor
  to avoid assuming `Some`.
  - Since they are optional in the protocol, we want to make sure any
  accessors properly handle the None case (getting the placeholder using
  the byte range in the text)
  - Preserve placeholders during protocol/app-server conversions using the
  accessor fallback.
  - Update TUI composer/remap logic and tests to use the new
  constructor/accessor.

• fix(core): don't update the file's mtime on resume (#9553)

  Remove `FileTimes::new().set_modified(SystemTime::now())` when resuming
  a thread.
  
  Context: It's awkward in UI built on top of app-server that resuming a
  thread bumps the `updated_at` timestamp, even if no message is sent. So
  if you open a thread (perhaps to just view its contents), it
  automatically reorders it to the top which is almost certainly not what
  you want.

• fix: prevent repeating interrupted turns (#9043)

  ## What
  Record a model-visible `<turn_aborted>` marker in history when a turn is
  interrupted, and treat it as a session prefix.
  
  ## Why
  When a turn is interrupted, Codex emits `TurnAborted` but previously did
  not persist anything model-visible in the conversation history. On the
  next user turn, the model can’t tell the previous work was aborted and
  may resume/repeat earlier actions (including duplicated side effects
  like re-opening PRs).
  
  Fixes: https://github.com/openai/codex/issues/9042
  
  ## How
  On `TurnAbortReason::Interrupted`, append a hidden user message
  containing a `<turn_aborted>…</turn_aborted>` marker and flush.
  Treat `<turn_aborted>` like `<environment_context>` for session-prefix
  filtering.
  Add a regression test to ensure follow-up turns don’t repeat side
  effects from an aborted turn.
  
  ## Testing
  `just fmt`
  `just fix -p codex-core`
  `cargo test -p codex-core -- --test-threads=1`
  `cargo test --all-features -- --test-threads=1`

• Fixed config merging issue with profiles (#9509)

  This PR fixes a small issue with chained (layered) config.toml file
  merging. The old logic didn't properly handle profiles.
  
  In particular, if a lower-layer config overrides a profile defined in a
  higher-layer config, the override did not take effect. This prevents
  users from having project-specific profile overrides and contradicts the
  (soon-to-be) documented behavior of config merging.
  
  The change adds a unit test for this case. It also exposes a function
  from the config crate that is needed by the app server code paths to
  implement support for layered configs.

• Persist text elements through TUI input and history (#9393)

  Continuation of breaking up this PR
  https://github.com/openai/codex/pull/9116
  
  ## Summary
  - Thread user text element ranges through TUI/TUI2 input, submission,
  queueing, and history so placeholders survive resume/edit flows.
  - Preserve local image attachments alongside text elements and rehydrate
  placeholders when restoring drafts.
  - Keep model-facing content shapes clean by attaching UI metadata only
  to user input/events (no API content changes).
  
  ## Key Changes
  - TUI/TUI2 composer now captures text element ranges, trims them with
  text edits, and restores them when submission is suppressed.
  - User history cells render styled spans for text elements and keep
  local image paths for future rehydration.
  - Initial chat widget bootstraps accept empty `initial_text_elements` to
  keep initialization uniform.
  - Protocol/core helpers updated to tolerate the new InputText field
  shape without changing payloads sent to the API.

• fix(core) Preserve base_instructions in SessionMeta (#9427)

  ## Summary
  This PR consolidates base_instructions onto SessionMeta /
  SessionConfiguration, so we ensure `base_instructions` is set once per
  session and should be (mostly) immutable, unless:
  - overridden by config on resume / fork
  - sub-agent tasks, like review or collab
  
  
  In a future PR, we should convert all references to `base_instructions`
  to consistently used the typed struct, so it's less likely that we put
  other strings there. See #9423. However, this PR is already quite
  complex, so I'm deferring that to a follow-up.
  
  ## Testing
  - [x] Added a resume test to assert that instructions are preserved. In
  particular, `resume_switches_models_preserves_base_instructions` fails
  against main.
  
  Existing test coverage thats assert base instructions are preserved
  across multiple requests in a session:
  - Manual compact keeps baseline instructions:
  core/tests/suite/compact.rs:199
  - Auto-compact keeps baseline instructions:
  core/tests/suite/compact.rs:1142
  - Prompt caching reuses the same instructions across two requests:
  core/tests/suite/prompt_caching.rs:150 and
  core/tests/suite/prompt_caching.rs:157
  - Prompt caching with explicit expected string across two requests:
  core/tests/suite/prompt_caching.rs:213 and
  core/tests/suite/prompt_caching.rs:222
  - Resume with model switch keeps original instructions:
  core/tests/suite/resume.rs:136
  - Compact/resume/fork uses request 0 instructions for later expected
  payloads: core/tests/suite/compact_resume_fork.rs:215

• TUI: collaboration mode UX + always submit UserTurn when enabled (#9461)

  - Adds experimental collaboration modes UX in TUI: Plan / Pair
  Programming / Execute.
  - Gated behind `Feature::CollaborationModes`; existing behavior remains
  unchanged when disabled.
  - Selection UX:
  - `Shift+Tab` cycles modes while idle (no task running, no modal/popup).
  - `/collab` cycles; `/collab <plan|pair|pp|execute|exec>` sets
  explicitly.
  - Footer flash after changes + shortcut overlay shows `Shift+Tab` “to
  change mode”.
    - `/status` shows “Collaboration mode”.
  - Submission semantics:
  - When enabled: every submit uses `Op::UserTurn` and always includes
  `collaboration_mode: Some(...)` (default Pair Programming).
    - Removes the one-shot “pending collaboration mode” behavior.
  - Implementation:
  - New `tui/src/collaboration_modes.rs` (selection enum/cycle, `/collab`
  parsing, resolve to `CollaborationMode`, footer flash line).
  - Fallback: `resolve_mode_or_fallback` synthesizes a `CollaborationMode`
  when presets are missing (uses current model + reasoning effort; no
  `developer_instructions`) to avoid core falling back to `Custom`.
    - TODO: migrate TUI to use `Op::UserTurn`.
